IMPROVEMENT IN VSTRAW-CUTTERS.

Specification forming part of Letters Patent No. 116,033, dated June 20,1`871.

To all whom t may concern:

Be it known that I, JOHN H. DIOKINSON, of Chicopee Falls, in the countyof Hampden and State of Massachusetts, have invented certain n ew anduseful Improvements in Straw-Gutters; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon which form a part of this specification.

The nature of my invention consists in the construction and arrangementof the cutting devices for a feed-cutter, as will be hereinafter morefully set forth.

In order to enable others skilled in the ar to which my inventionappertains to make and use the same., I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a side elevation, partly in section, and Fig. 2is a t'rontview of my machine.

A A represent the standards at the front end of thefeed-box B, and towhich the cutting device is attached. This cutting device consists oftwo rollers, C I), connected by means of gear-wheels, as shown. Thelower roller C is provided with a series of flanges, a., running inspiral form around the same, the outer edges of said lian ges being dator forming a dat surface. The upper rollerI) is'also provided withspiral nges b b; but said lianges run in opposite direction to those onthe lower roller, and their outer edges, instead of being iiat, arebeveled on one side; or the entire lian ge is beveled on one side, whilethe other side is at all points perpendicular with the center of theroller. On these perpendicular sides of the tlanges b bare attached spiralknives or cutters d d. The two rollers (l I) are so arranged that, asthey revolve in opposite directions, each knife or cutter d will comeagainst the outer flat-surface edge of a ange, a., commencing at oneend, and continuing spirally along the entire flange and knife to theother end, making at all times a surface and draw-cnt. Upon one of thejournals of the lowerroller C is a crank, E, by means of which therollers are revolved; and on the opposite journal of the upper roller Dis a flywheel, G, as shown. This arrangement of 'surface-cut cuttingdevice is-applicable to any feed-cutter, as well .as 'to many othercutters. Having thus fully described my invention, what I claim as new,and desire to secure by Letters Patent, is-

The roller D, with its flat-faced spiral anges, in combination withroller G, furnished with square-faced spiral cutters a c, so arrangedthat the faces of the cutters will press against those of the flanges,and, by the -more rapid motion of the former over the latter, impart asurface draw-cut upon the straw passing between the rollers,substantially as described.

In testimony that I claim the foregoing as my own I afiix my signaturein presence of two witnesses.
